Daniel Worley commented on SOLR-14151:
--------------------------------------
I've been testing these updates against some plugin code that utilizes a custom
encoder for the DelimitedPayloadTokenFilterFactory. It appears that Lucene
level code does not pick up on loaded packages. I believe this is due to the
SolrResourceLoader defaulting to a list of hardcoded packages when a list of
subpackages is not provided which will be the case with Lucene level code.
To reproduce you could add a dummy PayloadEncoder to your sample package then
try using it on a DelimitedPayloadTokenFilterFactory in
TestPackages::testSchemaPlugins, something like:
{{" 'filters' : [\{ 'class':'solr.DelimitedPayloadTokenFilterFactory',
'encoder':'schemapkg:my.pkg.MyEncoder' }]\n";}}
> Make schema components load from packages

> <fieldType name="mytype1" class="pkg1:my.pkg.FieldTypeImpl">
> <analyzer type="index">
> <tokenizer class="pkg2:my.pkg2.MyTokenizerFactory"/>
> <filter class="pkg2:my.pkg3.MyFilterFactory" generateWordParts="1"

> * When a package is updated, the entire {{IndexSchema}} object is refreshed,
> but the SolrCore object is not reloaded
> * Any component can be prefixed with the package name
> * The semantics of loading plugins remain the same as that of the components
> in {{solrconfig.xml}}
> * Plugins can be registered using schema API
